What comes back
We return the XML — that is the invoice, and that is what has legal standing. The preview is the same file read by a person.
/invoicing/validate also accepts UBL 2.1 and PDF/A-3 as input, but
/invoicing/generate always produces XRechnung CII — one syntax out, regardless of what you send in.
That is the whole integration. One endpoint, one call.
